leak tests: mark most gettext tests as passing with SANITIZE=leak

Mark all but one tests that match "*gettext*" as passing when git is compiled
with SANITIZE=leak. They'll now be listed as running under the
"GIT_TEST_PASSING_SANITIZE_LEAK=true" test mode (the "linux-leaks" CI
target).

In the case of "t0202-gettext-perl.sh" this isn't very meaningful as
most of the work is on the Perl side, but let's mark it anyway.
